and State of New Jersey h are invented certain new and useful Improvements in l-leating Devices" for Automobile-ill, gines, of which the following is a speeificetion.

This invention has as its object to pro vide a device for maintaining a circulation. of hot Water through the ra later and water jacket oi? an automobile engine so as to pre- "vent freezing of the Water when the auto mobile left standing in the cold oris left standing in an unheated garage,

It is one aim of the invention to so con struct the device that the same may he readily placed in 0 ation and thensethereofprior to cranking of the engine Another aim of the invention is to inro-- vide a device of the class mentioned. which may be manufactin'ed. eit low cost and which Will be economicel, in the coneuinption of fuel.

'lttl eeetional View on ery perspeotrolling the and the fleet 'e. int radiator by for the numeral 4:

hie

the b ottrnn the pipe is conne bottom of th; sei from the up: and is enlar :r 1 point it d W tin the 1 wiiator end water he radiator hatch to the Water jacket 3 and thence again through the said pipe 4;. In or to unsure of flow of Water along the couric stated the pipe I} is provided a suit-' ebledistance rcarwardly of the point of its communication with the radiator 2 with a downward bend 8 and from this bond is inclined upwardly to its said point of cominunicaticm with the radiator as indicated by the nul'nernl The heater proper Which will now be described, is so located that the flame therefrom will play upon the pipe at at apoint immediately in advance of the bend 8 and it will be understood that due to the provision of this bend and the upwerd inclination of the pipe from the said bend toward its point of communication with the radiator 2, the Water heated Within the. pipe will iioW toward the forward end thereof or, in other "Words, toward the said radiator and. will not have a tendency to How beck past the bend 8. a.

The heater proper comprises a hollow oil reservoir or font 10 provided with a coi er' 11 removably secured in place as for eX-' ample by screws 12. At one slde the font.

10 is provided With an attaching bracket 13 edapted to be secured to I any convenient part of the automobile so as to position the heater beneath the portion 9 of the pipe 4. The cover 11 of the heatercarries a burner 1t and the cover is further, DIO-Vidfld with a Wish tube 15 the lower'end of which surrounds the upper end of a Wick tube 16 which extends upwardly Within the font 10 centrally thereof, a wick 17 of the tubular type being slidably received between the said Wick tubes. The burner 14 is provided with the usual stem 18 for raising and lowering the Wick as in the case of the ordinary oil lamp. in its bottom the font 10 is provided with a drain. valve 19 which may be opened to permit opt: drawing oil of the liquid ifuel within the font and any sediment Which might eccunnilete in the bottom oi? the font.

in order that the tent may be supplied with liquidifuel and that the supply to the font may be controlled by the driver of the rnechine, a liquid fuel reservoir 20 is mounte.

the interior of the said casing, which in turn is in communication, as indicated at 26, with the interior of the font. The numeral 27 inof the stem dicates a float which is preferably annular in form and which surrounds a vtubular downward extension 28 of the cover 11 which extension in turn surrounds the wick tubes 15' and 16 as clearly shown in 'Fi 2 of the drawings The float 27 is provide at one side with a stem 29 which is pivotally mounted between its ends as at'30.w1thin the upper portion of the casing 23, the float being located at one side of the pivot 30 and the said stem being provided at the other side of the, pivot with an opening 31 loosely receiving the stem'32 of a needle valve 33 which needle valve normally occupies the seat 25 but is adapted upon fall of the float 27 to be lifted from the said seat whereby to permit liquid fuel to flow from the pipe 21 in to the font 10. The lift of the needle valve may be varied by adjusting a nut 34 which is threaded onto the upper end of the valve stem 32 and coacts with the upper side 29 at the upper end of the opening 31.

From the foregoing description of the in vention it will be understoodthat when the automobile is to be left standing in the cold or is to be left in an unheated garage, the oil heater herein described may be placed in operation and the heat from the flame will heat the water in the pipe 9, causing the heated water to rise into the radiator 2 and thence flow through the pipe '6 to the water jacket 3 and back again into the'first mento permit of the flow to the font of more of the liquid fuel. Therefore, the device is entirely automatic in itsaction and may be left over night .without further attention on the part of the owner of the machine.

In order that access may be had to the interior of the valve casing 23 for the purpose of adjusting the nut 34, the upper end of the said casing is preferably closed by. a. screw cap 35.

At the lower end of the portion 9 of the pipe 4, the pipe is provided with a water chamber 8 which serves the purpose of a boiler in which'the water may be heated before circulating through the sysem.

Having thus described the invention, what i is claimed as new is: N

In a liquid fuelburner of the class described, a font, a'wick tube extending downwardly into the font, a float arranged within the font and surrounding the wick tube, a stem at one side of the float pivotall mounted within the font at one side thereo the font at its said side having an inlet provided with a valve seat, a valve disposed to normally rest bygravity upon the seat and having an upstanding stem, a collar carried by the stem of the float at the other side of the said pivot and loosely surrounding the stem of the valve, the said valve stem being threaded, and at nut adjustably fitted upon the said valve stem and constituting an abutment for the said collar.

In testimony whereof I afiix my signature.
